Two identical short bar magnets are placed at 120

Asked by admin @ 20/08/2021 in Physics viewed by 370 People

Two identical short bar magnets are placed at 120° as shown in the figure. The magnetic moment of each magnet is M. Then the magnetic field at the point P on the angle bisector is given by

(1) µ04π·Md3 (2) µ04π·2Md3 (3) µ04π·2√2Md3 (4) Zero

Answered by admin @ 20/08/2021

Suppose P is at the axial line of the bar magnet at a distance r ,

Therefore,

B on the axial line,

B = u.•/4π(2M/r³)
